Hi again After Eric Dumazet fixed lockdep issue, one warning disappeared, but still card is not working. It is not only for that model, i faced this problem for many realtek cards. Probably as i mentioned something specific (such as ifplugd interface polling) causing that, but it is making almost all r8169 cards unusable for me. Some additional dmesg info,that maybe will be helpful: [ 22.683789] r8169 0000:03:00.0: irq 43 for MSI/MSI-X [ 22.685025] r8169 0000:03:00.0 eth0: RTL8168d/8111d at 0xf8afe000, 00:27:0e:27:32:41, XID 081000c0 IRQ 43 [ 22.685192] r8169 0000:03:00.0 eth0: jumbo features [frames: 9200 bytes, tx checksumming: ko] [ 22.760348] r8169 0000:03:00.0 eth0: link down [ 24.340901] r8169 0000:03:00.0 eth0: link up [ 48.720016] ------------[ cut here ]------------ [ 48.720060] WARNING: at net/sched/sch_generic.c:255 dev_watchdog+0xcd/0x121() [ 48.720101] Hardware name: [ 48.720133] NETDEV WATCHDOG: eth0 (r8169): transmit queue 0 timed out [ 48.720172] Modules linked in: r8169 nf_nat_pptp nf_nat_proto_gre nf_conntrack_pptp nf_conntrack_proto_gre cls_flow cls_u32 em_meta cls_basic xt_dscp xt_hl ifb cls_fw sch_tbf sch_htb act_ipt act_mirred xt_nat xt_REDIRECT ipt_REJECT xt_TCPMSS ts_bm xt_string xt_connmark xt_DSCP xt_mark iptable_mangle iptable_nat nf_conntrack_ipv4 nf_defrag_ipv4 nf_nat_ipv4 nf_nat nf_conntrack iptable_filter 8021q garp stp mrp llc loop tulip sky2 via_velocity via_rhine sis900 ne2k_pci 8390 skge libphy 8139cp 8139too e1000e ptp pps_core e1000 e100 usbhid [last unloaded: r8169] [ 48.720257] Pid: 3, comm: ksoftirqd/0 Not tainted 3.9.2-build-0065 #4 [ 48.720260] Call Trace: [ 48.720267] [<c012bee5>] warn_slowpath_common+0x77/0x8e [ 48.720273] [<c0385261>] ? dev_watchdog+0xcd/0x121 [ 48.720279] [<c0385261>] ? dev_watchdog+0xcd/0x121 [ 48.720284] [<c012bf78>] warn_slowpath_fmt+0x2e/0x30 [ 48.720289] [<c0385261>] dev_watchdog+0xcd/0x121 [ 48.720295] [<c0136102>] call_timer_fn+0x69/0xdc [ 48.720300] [<c0136099>] ? cascade+0x5c/0x5c [ 48.720312] [<c03e5081>] ? _raw_spin_unlock_irq+0x22/0x26 [ 48.720315] [<c0385194>] ? netif_tx_unlock+0x41/0x41 [ 48.720318] [<c01362e6>] run_timer_softirq+0x171/0x1ab [ 48.720321] [<c0385194>] ? netif_tx_unlock+0x41/0x41 [ 48.720325] [<c0131963>] __do_softirq+0x98/0x153 [ 48.720328] [<c0131a45>] ? run_ksoftirqd+0x27/0x38 [ 48.720331] [<c0131a39>] run_ksoftirqd+0x1b/0x38 [ 48.720334] [<c0147dc6>] smpboot_thread_fn+0x10f/0x114 [ 48.720339] [<c01421f5>] kthread+0x6b/0x70 [ 48.720341] [<c0147cb7>] ? __smpboot_create_thread+0xd3/0xd3 [ 48.720345] [<c03e5a77>] ret_from_kernel_thread+0x1b/0x28 [ 48.720348] [<c014218a>] ? __init_kthread_worker+0x47/0x47 [ 48.720350] ---[ end trace 535f1a8b707a82d3 ]--- [ 48.725335] r8169 0000:03:00.0 eth0: link up [ 54.725270] r8169 0000:03:00.0 eth0: link up [ 60.725270] r8169 0000:03:00.0 eth0: link up [ 66.725268] r8169 0000:03:00.0 eth0: link up [ 72.725269] r8169 0000:03:00.0 eth0: link up [ 78.725268] r8169 0000:03:00.0 eth0: link up [ 84.725270] r8169 0000:03:00.0 eth0: link up [ 90.725266] r8169 0000:03:00.0 eth0: link up [ 96.725268] r8169 0000:03:00.0 eth0: link up [ 102.725278] r8169 0000:03:00.0 eth0: link up [ 108.725271] r8169 0000:03:00.0 eth0: link up [ 114.725270] r8169 0000:03:00.0 eth0: link up [ 120.725269] r8169 0000:03:00.0 eth0: link up [ 126.725269] r8169 0000:03:00.0 eth0: link up [ 132.725272] r8169 0000:03:00.0 eth0: link up [ 138.725270] r8169 0000:03:00.0 eth0: link up [ 155.028457] r8169 Gigabit Ethernet driver 2.3LK-NAPI loaded [ 155.028789] r8169 0000:03:00.0: irq 43 for MSI/MSI-X [ 155.029997] r8169 0000:03:00.0 eth0: RTL8168d/8111d at 0xf8c50000, 00:27:0e:27:32:41, XID 081000c0 IRQ 43 [ 155.030166] r8169 0000:03:00.0 eth0: jumbo features [frames: 9200 bytes, tx checksumming: ko] [ 157.707319] r8169 0000:03:00.0 eth0: link down [ 157.707378] r8169 0000:03:00.0 eth0: link down [ 159.372510] r8169 0000:03:00.0 eth0: link up [ 166.628362] r8169 Gigabit Ethernet driver 2.3LK-NAPI loaded [ 166.628679] r8169 0000:03:00.0: irq 43 for MSI/MSI-X [ 166.629880] r8169 0000:03:00.0 eth0: RTL8168d/8111d at 0xf8c76000, 00:27:0e:27:32:41, XID 081000c0 IRQ 43 [ 166.630052] r8169 0000:03:00.0 eth0: jumbo features [frames: 9200 bytes, tx checksumming: ko] [ 167.747589] INFO: trying to register non-static key.
